Black Ball Ferry Line
Grade A · 98.2 / 100
Unchanged since 2026-07-08.
What this grade measures
The quality of the schedule data this agency publishes for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.
Progress this period
No newly cleared items this period. The score and trend above reflect where the feed stands today.
What needs attention next
Three improvements, in priority order, each sized so the board can see what it is approving:
Remove past service periods the next time you export the feed.
Some service calendars in the feed have already expired. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Estimated effort: One setting in most export tools.
Agencies here usually clear this within about 1 week (based on 61 observed fixes).
Where this agency stands
Ahead of 100% of all tracked agencies, and ahead of 99% of small agencies nationwide.
